Malaysian authorities say a military helicopter crashed into a school in a rural area on Borneo island, injuring at least 22 people including students.

The father of a British woman who is detained for posing naked on a mountain says she knows what she did was "stupid and disrespectful" and is sorry for the offence she has caused to Malaysians.

It may be just a mountain to some, but pulling down your pants at sacred sites is not something that's giggled at by the people who hold such places, like Malaysia's Mount Kinabalu, in special regard.
